Tool holder
Clamp the lathe tool into the tool holder.
The lathe tool needs to be clamped as short and tight as possible when turning in order to be
able to absorb the cutting force during the chip formation well and reliably.
Adjust the height of the tool. Use the tailstock with the centering point in order to determine the
required height. If necessary, put the steel washers beneath the lathe tool to achieve the
required height.

Lathe spindle fixture
WARNING!
Do not clamp any workpieces that exceed the permitted chucking capacity of the lathe
chuck. The clamping force of the chuck is too low if its capacity is being exceeded. The
clamping jaws may loosen.
Only use lathe chucks designed for the speed of the machine.
Do not use lathe chucks with an external diameter that is too large.
Please ensure that lathe chucks are manufactured to EN 1550 standards.
ATTENTION!
During dismantling, the lathe chuck can fall onto the machine bed and damage the guide
rails. Place a wooden board or other suitable object on the machine bed to prevent
damage.
INFORMATION
The lathe chuck guard does not have to be removed for this. Turn the lathe chuck to the appro-
priate position to loosen the fixing screws with the spanner.
